it brought many new features such as native multimedia support and the ability to handle file manipulation, geolocation, drag, and drop.

Which browser has the highest support for HTML5?

While you would expect most browsers to have HTML5 support, the level of HTML5 compliance differs from one browser to another.

The browser with the highest support for HTML5 is Opera One. This is because it is frequently updated to meet the latest requirement of markup language.

How do I know if my browser supports HTML5?

There is no need to find out if your browser supports HTML5. This is because all modern web browsers support the markup language out of the box. So, there’s no need to install or configure anything.

However, not all browsers offer the same support for HTML5, so if you want the best support, it’s advised to use Opera One.

The Opera One browser is fully compatible with HTML5 but has many other great features. First, a built-in ad blocker will speed up your webpage loading by blocking tracking cookies and scripts.

How do I make my browser support HTML5?

There are new features in HTML5 that are absent in the older versions from HTML4 down. If your browser does not support HTML5, below are some of the compatibility issues you might be facing:

  • Form feature issues: HTML5 has new input and output attributes that cannot be found in the earlier versions. These attributes are email, URL, and datetime-local, among others. So if your browser does not support HTML5, it will have problems with these features.
  • Semantic Tags: HTML5 has dropped some presentational elements like big, font, and center. So you shouldn’t expect it to work.
  • Storage Capability: The HTML5 standard has a storage capability that allows browsers to store data on the user side. This data is more long-lasting than the cookies. However, this feature only works in the latest browsers.

All in all, HTML5 has been around for years, and all modern browsers support it. So, you don’t have much to worry about regarding compatibility.
